Anomalous behaviour of transient creep in commercially pure aluminium

Czechoslovak Journal of Physics B Aims and scope

Abstract

Transient creep of pure and commercial aluminium was studied under a constant stress of 18·6 MPa at different temperatures ranging from 613 to 698 K. The anomalous values of transient creep parametersβ, n ranging from 0·003–0·055 (±0·001) and 0·5–1·0 (±0·05) respectively, which were found in this temperature rangs, might bs ascribed to the superplastic behaviour of pure and commercial aluminium. The activation energy of transient creep for pure Al was found to be about (2·4 +0·07) × 10−22) kJ/atom. characterizing a dislocation glide-cross slipping mechanism.
